Michel Raulier: The Nail Tree of Stambruges Tree worship in our region is very ancient. Proof of this is the discovery in Blicquy, in the place called "Ville d'Anderlecht," of a set of 120 posts up to 90 cm in diameter. These may have served as supports for offerings, as evidenced by the numerous iron pins found in the filling holes. This could correspond to an artificial sacred grove housing deities, similar to Lucan's description of petrified forests in Pharsalia. In the past, trees, with their longevity and majestic shape, aroused a sense of sacredness in the minds of our ancestors. They were also believed to be capable of helping people solve their problems, particularly health problems. Many customs exist: walking around the tree, driving nails to fix the ailment, and tying cloths or fabrics to bind it. These trees were often Christianized by the installation of religious images or a chapel nearby. One example among others is that of Notre Dame de Foy. In Foy, near Dinant, a woodcutter discovered a 15th-century statuette in the heart of a very ancient oak tree in 1609. Long forgotten, the figurine bearing the image of the Virgin had been placed in a niche carved into the trunk. Over time, the wood completely covered it and erased its memory. In Stambruges, there is one of these remarkable trees, and beside it is a chapel, called "the chapel of Erconpuch" or, by another name, "the chapel of Arc-au-Puche," dedicated to the Virgin Our Lady of Arc-au-Puits, formerly called the Virgin of the Woods.

September 27, 2022, Le Caillou-qui-Bique

A legend has been perpetuated for generations on this 25 meter high stone planted on a ridge (in patois we say that it rocks). A little step back in time... Saint-Ghislain completes the construction of its abbey. The devil decides that he will take advantage of the inauguration day to destroy the abbey and its occupants, by throwing an enormous stone found in the Pyrenees at the community. An angel warns Saint-Ghislain of the imminent danger weighing on the abbey. He gathers as many pairs of worn shoes as possible, which he slips into a huge bag and takes to the road to meet the evil one. Coming across a poor fellow in rags with holes in his shoes at this place, the devil, quite exhausted by the heavy load, questions him: “Is the abbey of Saint-Ghislain still far away? ". - “I’m coming from there, if it’s far!” » replies the old man while emptying his bag, filled with threadbare shoes, in front of the devil. Discouraged and disappointed, Satan preferred to give up, dropping his heavy stone on the ground and walking away blaspheming, fooled by the subterfuge. An hour and a half. N.B.: some historians say that this is the legend of Saint Remacle, during the construction of Stavelot Abbey. You are therefore free to substitute Remacle for Saint-Ghislain since this substitution does not modify the spirit of the story. In both cases, the devil is defeated.
